H(t) = -16t² + 16 t + 480
Factor out -16
-16(t² - t - 30)
t² - t - 30
(t + 5)(t - 6) ⇒ t(t-6) + 5(t-6) ⇒ t² -6t + 5t - 30 ⇒ t² - t - 30
t + 5 = 0 t - 6 = 0
t = -5 t = 6
The value of t is either -5 or 6 however time can't be measured in negative form; then, it took Rose 6 seconds to hit the water.
Answer:
x^2 -10x+25
Step-by-step explanation:
(x − 5)^2
(x-5)(x-5)
FOIL
first x*x = x^2
Outer -5 *x = -5x
inner -5*x = -5x
last -5*-5 =25
Add them together x^2 -5x-5x+25
Combine like terms x^2 -10x+25
I believe that the answer to the question would be 4.5
You divide 500 by $50 to get 10; the school sold 10 yearbooks that year if you’re looking for that as an answer.
